What you see: A 1908 poster touting the talent of magician Chung Ling Soo. Potter & Potter estimates it at $5,000 to $6,000.

Who was Chung Ling Soo? Born William Ellsworth Robinson in Westchester County, New York in 1861, he was a behind-the-scenes designer of magic tricks for headliners Harry Keller and Alexander Herrmann before he struck out on his own. Around 1900, while in Europe, he adopted the Chung Ling Soo persona. He went to great lengths to preserve the illusion, limiting his speech on stage to the occasional bit of broken English and relying on an interpreter to talk to journalists. He died in 1918 at the age of 56.

Are vintage posters featuring Chung Ling Soo rare in general? “Yes, I would say they’re uncommon or scarce,” says Gabe Fajuri, president of Potter & Potter. “The one we’re talking about is a bit harder to find than the others.”

Other famous magic posters of the era show the magician receiving supernatural help. Here, Chung Ling Soo shows what he purports to be the source of his magical talent–his own hands. No supernatural help required. Is this an unusual theme for a vintage magic poster? “There are plenty of portraits [on magic posters],” he says. “We have sold other posters of magicians showing their hands and doing maneuvers, but they’re not as artful as saying ‘My Ten Assistants.’ It got reworked by Ricky Jay into ‘My 52 Assistants.’ It’s not the only example of a magician showing sleight of hand on a poster or referring to sleight of hand, or how they accomplish their tricks.”

Is Robinson, akaChung Ling Soo, the first person to move from a backstage magic designer role to an on-stage magician role? “He was the great secret weapon for these guys. He was designing and inventing illusions,” he says. “In any professional situation, someone will say, ‘Oh yeah, my boss doesn’t know what he’s doing. I can do a better job.’ He proved he could do as good a job. It took work, and a different persona, but his success is pretty significant.”

Would you talk about how Robinson/Soo died? “He was performing a bullet catch trick in London, England. It was one of the big theatrical showpieces of his performance,” Fajuri says. “I wrote a long time ago that instead of catching the bullet on a plate, he caught the bullet in his chest. They brought the curtain down, and he died not long after.”

Was he the first magician to die doing the bullet catch trick? No. “It wasn’t a new trick. It had been around for decades [by 1918, when Robinson/Soo died], and it had killed people,” he says. “Keller advised Houdini against it in a very famous letter. Robinson did have experience backstage with the trick, and he was familiar with other ways of performing the feat. There’s controversy surrounding what happened. Not thoroughly checking his props led to his demise. It’s a tragic story. He was at the top of his game.”

How rare is the ‘Chung Ling Soo and His Ten Assistants’ poster? “I haven’t had one before in ten years of auctioning magic memorabilia,” he says, adding that he’s aware of at least six copies. “This one was owned by a magician in England. He died years ago, and his family consigned it. It’s in A- condition. Very little was done to it. You’re not going to get much better than this.”

What else makes this Chung Ling Soo poster special? “This is more scarce. The image is realistic. The turn of phrase is nice, and the colors are not garish,” he says. “It has a lot going for it by way of aesthetics, the story, and the man it depicts. It has a little bit of everything.”
